In principle, quantum key distribution (QKD) offers information-theoretic security based on
the laws of physics. In practice, however, the imperfections of realistic devices might …

Quantum key distribution (QKD) is the first quantum information task to reach the level of
mature technology, already fit for commercialization. It aims at the creation of a secret key …

The superposition principle plays the most central role in all considerations of quantum
information, and in most of the" gedanken" experiments and even the paradoxes of quantum …

This paper prove the security of the Bennett-Brassard (BB84) quantum key distribution
protocol in the case where the source and detector are under the limited control of an …

We report on the experimental implementation of a Bennett-Brassard 1984 (BB84) protocol
type quantum key distribution over a 144 km free-space link using weak coherent laser …

I prove the security of quantum key distribution against individual attacks for realistic signals
sources, including weak coherent pulses and down-conversion sources. The proof applies …

We report a demonstration of quantum key distribution over a standard telecom fiber
exceeding 100 km in length. Through careful optimization of the interferometer and single …

Quantum key distribution (QKD) allows two remote parties to grow a shared secret key. Its
security is founded on the principles of quantum mechanics, but in reality it significantly …

A novel quantum cryptography scheme is proposed, in which a single photon is prepared in
a linear superposition state of three basis kets. A photon split to three pulses is sent from …
